Abstract
For recovery of iron oxides from disseminated iron ore, the flotation technology is developed based on using organophosphorus compounds as primary collectors. Selective preliminary removal of impurities and iron oxide flotation from wet magnetic separation tailings and directly from fine disseminated hematite ore ensures production of quality hematite-martite concentrates with the iron content of 64–66%. The option of by-production of gold from quartz present in hematite flotation tailings is illustrated.
